Web-norm may not be robust, and the l. 1-norm can be preferred (Claerbout and Muir, 1973; Brossier et al., 2010). Several studies have already demonstrated the robustness of the l. 1-norm for noisy data. Pyun et al. (2009) showed that the l. 1-norm flattens the amplitude spectra of the residual wavefield preserving the phase spectra, which minimizes
WebA simple choice of robust measure is the l 1 norm. Denoting the residual (misfit) components by ri;i D1;::::N(Nbeing the number of data points), the l 1 norm misfit function of the residual vector is PN iD1 jrij. This function is not smooth: it is singular where any residual component vanishes. As a result, thick masking tapeWebA mixed-norm parameter is introduced to determine the relative importance between the l1norm and l2norm functional, which is a function of the kurtosis of the errors. The novelty of the proposed mixed-norm algorithm is that no knowledge of the seismic errors is required. sail away with me guitar tab brian wilsonWebJan 1, 2003 · We propose to minimize the Huber function with a quasi-Newton method that has the potential of being faster and more robust than conjugate-gradient methods when solving nonlinear problems.
